Port Role Displays the role that the port plays in the desired instance.
Root Port: Indicates that the port is the root port in the desired instance. It
has the lowest path cost from the root bridge to this switch and is used to
communicate with the root bridge.
Designated Port: Indicates that the port is the designated port in the desired
instance. It has the lowest path cost from the root bridge to this physical
network segment and is used to forward data for the corresponding network
segment.
Alternate Port: Indicates that the port is the alternate port in the desired
instance. It is the backup of the root port or master port.
Backup Port: Indicates that the port is the backup port in the desired
instance. It is the backup of the designated port.
Master Port: Indicates the port provides the lowest root path cost from the
region to the root bridge in CIST. In CIST, each region is regarded as a switch,
and the master port is the root port of the corresponding region.
Disabled: Indicates that the port is not participating in the spanning tree.
Port Status Displays the port status.
Forwarding: The port receives and sends BPDUs, and forwards user traffic.
Learning: The port receives and sends BPDUs. It also receives user traffic,
but doesn’t forward the traffic.
Blocking: The port only receives and sends BPDUs.
Disconnected: The port has the spanning tree function enabled but is not
connected to any device.
LAG Displays the LAG which the port belongs to.
